/**
 * Marker indicating that a field is quasi 'final' for all practical purposes,
 * AFTER it has been set to a value that is not null, 0, etc.
 * because it is only initialized once and only inspected after proper initialization.
 * It is up to the programmer to maintain this invariant!
 * 
 * Note that reading the field's value can only occur AFTER bootstrapping.
 * Therefore, there is no constant folding during bootstrapping.
